TVS600 & TVS600A Command Reference

 When CALC<n>:WMP:GATE is set to OFF, the measurement zone becomes the

entire waveform record. The measurement zone defined by the 

:GATE

command parameters is ignored.

All measurements included in the CALC block are affected by these commands,
but gating for each CALC block is settable independently.

The CALCulate<n>:WMParameter:EDGE command selects the waveform edge
that the measurement is taken on for these edge-based measurements:

 CROSs, NCROSs, and PCROSs

 DELay

 FTIMe and RTIMe

 COPulse

The CALCulate<n>:WMParameter:SLOPE command selects the polarity of the
edges used in DELay measurements; the polarity of the edge used for the other
edge measurements is determined implicitly (for example, RTIME use positive
slope, etc.).

When 

CALC:WFM:GATE is set to OFF, the waveform analyzer finds the edge within

the entire waveform record; when set to 

ON, the waveform analyzer finds the

edge with in the measurement zone.

The automated measurements are defined and calculated as follows.

Amplitude = High – Low
